[PATCH] [ASan/Win] Use clang rather than clang-cl by default for lit tests. Make Windows-only tests explicitly use clang-cl.

[Timur Iskhodzhanov]

1) clang crashes on windows with -g [fixable]
2) we had a chat with Kostya and decided it's the right thing to test ASan
with just glto to be sure it gives us enough DI
